Independent geospatial & software studio
Remote sensing data processing and scientific software development for researchers and small teams. Clear methods. Practical tools. Work you can build on.
01 / Selected work
Public projects developed by Yuhao Wang. Explore the source, documentation and current capabilities.
Geospatial software
A coastal tide and vertical-datum toolkit for bringing elevation data and tide simulations into a consistent research workflow. FES2022b tide simulation, MSL / EGM2008 / WGS84 datum conversion, and batch DEM conversion with resume support.
View projectAn open-source Zotero reading assistant with selection translation, contextual AI questions, paper digests and note export.
View projectA self-hosted bilingual PDF paper reader: paragraph translation, source-page zoom, and separate models for translation and Q&A. Run it yourself with Docker or locally.
View projectOpen code, inspectable methods. Current status: PaperPilot v1.0.2 for Zotero (October 2026); PaperPilot Web v0.2.1, self-hosted (October 2026); CoastTideX v1.7.1 codebase (documentation updated September 2026). Claude API integration is in planning and evaluation, not a current feature.
More on GitHub02 / How we can help
Focused project work, from a well-defined data problem to a documented software handoff.
Prepare, align and process raster and spatial datasets for research. Define the study area, check coordinate and height references, and make the processing repeatable.
Typical deliverablesProcessed datasets, reusable scripts, quality checks and a methods note.
Turn a research method or an existing script into a tool others can use. Build command-line workflows, desktop interfaces, data utilities and research plugins.
Typical deliverablesSource code, an agreed setup or build, tests and usage documentation.
Scope and prototype useful AI features around documents and scientific tools. PaperPilot is an existing example; Claude API integration for geospatial workflows is being planned and evaluated.
Engagement scopeA defined prototype, documented data handling and evaluation against agreed examples.
03 / Working together
Start with a concrete question and a representative sample. Agree on what success means before expanding the work.
Discuss your data, constraints and expected outputs. Identify what is feasible and what needs investigation.
Develop the workflow on representative data. Review assumptions, edge cases and the resulting outputs together.
Hand over the agreed code, results and documentation so your team can understand and continue the work.
The person behind the work
HaoHorizon is led by Yuhao Wang, the developer behind CoastTideX and PaperPilot. The focus is practical: useful geospatial workflows, research software and carefully evaluated AI applications.
When you get in touch, you speak directly with the person developing the work.

Send a short description of your question, data and intended deliverable. We can discuss scope, feasibility and next steps.
hello@haohorizon.comNo need to send sensitive data in your first message.
Yes. A narrowly defined processing step, software utility or feasibility study is a useful place to start. Scope and terms are discussed before work begins.
CoastTideX source and documentation are public. PaperPilot v1.0.2 has a published Zotero add-on package. Each project page links to the relevant repository and setup instructions.
Yes. We can scope an AI-assisted document or tool workflow and evaluate it against representative examples. Provider access, data handling and human review need to be agreed. PaperPilot offers an existing example; future Claude integration is in planning and evaluation.
